METHOD FOR FILLING 'USUBTERRANEAN CAVI'LIES.-v

To all who-m t 'may concern',A l

Be it known that we, ADoLPH GoEBL, a

' subject of the .Government of CzechoSlo-- vakia, and MICHAEL A. EIBE'N, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Methods for Filling Up Subterranean Cavities, of which the following is a specification.

This invention relates to -a method for vfilling up subterranean cavities. This is frequently desirable under certain conditions, as where a mine working is to be abandoned, or a portion of a mine is to be illed up. ,This latter condition is often desirable where gas develops in a mine working, or where there is danger of collapse or, caving ofthe upper layers or roof of a mine.

The object ofthe present invention is to provide means for lling such cavities in a safe and convenient manner.

The Aprocess is illustrated in the accom? panying drawing, which is a section illustrating the apparatus. Referring thereto, 1

indicates the filling or the cavity to be filled.

This. cavityy is primarily cut 0H from| the rest of the mine by atemporary wall 8.' A suitable shaft is sunk to receive a pipe sysf tem 7 extending from the top of the ground down into the mine and through the wall 8. A mixture of earth and water is supplied to this pipe 7 by any suitable means, or for foundations or the likea cement mixture may be supplied. We have shown a mixture of vearth andA Water which is iiowed into the pipe as from a bank 6 by means of `a water `jet 3 which washes the bank and carries with itsuliicient earth. This jet may be supplied by a pumpffrom a pool 4,01' in any other suitable way.

Speoication bf Letters Patent. Patented Jan, 17, 1922, Application manly 2s, 1821. serial No. 485,113.

The mixture of earth and water iows down through the pipe 7 and intothe cavity 1. The water will leak out through the temporary wall -8 and the earth will remain in position within the cavity. The water may be collected in a pool 9, from which it may be pumped by a pump 1Q and* pipe 11 to the surface. y discharging the same into the pool 4 it can be. used repeatedly.

'By the means described a sufficient amount of earth canbe quickly and readily deposited in a subterranean cavity in suiiicient-,quantities to fill the same.

We claim.l

1. The process of filling a subterranean -cavity comprising forcing surface soil by A to cause a iiowfofmixed earth and .Water vfromthe surface of the ground through said pipe and into said cavity, said water leaking through said Wall, and meansto pump said. water from said cavity to the surface of the ground. y

In testimony whereof, we do aiiix our signatures in presence of two witnesses.
